The present application discloses a blood transfusion device, which comprises a flushing tube, a flushing needle tube and a blood transfusion needle tube. One end of the flushing tube is connected with the flushing needle tube, and the other end of the flushing tube is connected with the blood transfusion needle tube; the blood transfusion needle tube is connected with a branch pipe, and the branch pipe is connected with the blood transfusion vessel; the inner part of the blood transfusion needle tube is provided with a check valve, which includes a blood transfusion needle tube. The first concave obstructor and the second concave obstructor with wall contact are close to the needle tip of the blood transfusion needle tube, the second concave obstructor is close to the branch tube, the first concave obstructor is provided with a first through hole, the second through hole is opened on the second concave obstructor, and the first concave obstructor is arranged between the second concave obstructor and the first concave obstructor. Floating ball. Connect the flushing tube, no longer need to take off the blood transfusion needle tube and then connect to the saline bottle for flushing, reduce the workload of operators; set check valve, check valve to prevent the return of saline to the needle tip, resulting in the next blood transfusion is not smooth, but also to prevent blood reflux.
【技术实现步骤摘要】
一种输血器
本技术涉及医用器械领域,具体涉及一种输血器。
技术介绍
输血器是临床医学中非常重要的医疗器械,特别是在急诊中,更是会常常用到,因为急诊患者中很大比例的都是车祸或者其他事故的患者,这些患者在治疗时都需要大量的输血,一般的输血器包括输血针管和与输血针管连接的输血管,一般输血前后需要用静脉注射生理盐水冲洗输血管道,这是因为生理盐水就是0.9%的氯化钠水溶液,它的渗透压值和正常人的血浆、组织液都是大致一样的,所以可以用作补液,不会降低和增加正常人体内钠离子浓度,对于需要源源不断的给患者输用血液的情况,前一袋血输尽后,需要用静脉注射生理盐水冲洗输血器,再接下一袋血继续输注。在对需要源源不断输血的患者输血时,输完一袋血后,需要将输血针管从血袋上取下,再插入到生理盐水瓶中,用生理盐水冲洗过后再输下一袋血,冲洗完成后再将输血针管从生理盐水瓶中取下,再插入到下一袋血袋中。这样的操作由于需要将输血针管不断的从血袋和生理盐水瓶中取下和插入,增加了操作人员的工作量;而且一般的生理盐水瓶中生理盐水的量非常大,可以进行很多次冲洗,所以在将输血针管从生理盐水瓶中取下的时候,生理盐水 ...
